There has long been professional and public concern about the overuse of radiography and computed tomography (CT) and the resultant excessive radiation exposure in patients with CSI. Guidelines for imaging potential cervical spine injury (CSI) Thus, the American College of Radiology Appropriateness Criteria: Suspected Cervical Spine Injury states that MDCT, not radiography, is now the primary, preferred, and most appropriate method of imaging suspected cervical spine injury in patients older than 14 years.

It has been shown that up to 20% or more of cervical fractures disclosed by MDCT are unapparent, overlooked, or simply missed on plain film radiographs of the cervical spine. C, Associated fracture of the posterior arch of C1. B, Fracture of the dens shown by MDCT sagittal reconstruction. Ī, Lateral cervical spine radiograph showing associated fracture of the posterior arch of C1. The associated fracture of the posterior arch of C1 is seen by both examinations ( Figure 6-1 A, C). The comparative difficulty of detection by radiography is shown by a fracture of the dens that is hard to see, if not impossible to identify, on the lateral cervical spine radiograph ( Figure 6-1 A ) but is clearly shown by the MDCT sagittal reconstruction ( Figure 6-1 B ). With these advances it became apparent that MDCT is more accurate and more efficient in the detection and depiction of spinal injuries. This permitted coronal and sagittal reconstructions of the entire length of the cervical spine in addition to the standard axial images. Computed tomography (CT) was first introduced in the 1970s but did not prove adequate for the evaluation of the acutely injured spine until the early 2000s with the introduction and perfection of multidetector CT (MDCT), with rapid exposures coupled with the development of immediate and readily accomplished multiplanar image reconstructions. Though traditional and long the mainstay of cervical spine evaluation, radiographs of the cervical spine now have a limited role in the initial assessment of cervical spine trauma.
